Port 6.x changes (graphql upload support and composer suggestion)

[homersimpsons]

This merges the following commits:

• 👽 Support ecodev/graphql-upload v8
• 📦 Suggest installing ecodev/graphql-upload (v7/v8)
• 📦 Fix middleware utils placement to be consistent with other files
• 📦 Resolve phpstan issue - PHP 8.4 deprecation
• 📦 Bump actions/cache to v5 to avoid failed CI with deprecated cache version

In the merge commit (conflicts) I moved the UploadMiddlewareUtils/ directory to src/ and I used get_debug_type instead of get_class

Well, phpstan does not seem happy anymore:

Parameter #1 $object of function get_class expects object, mixed given.

But $dummyResponseWithRequest is guaranteed to be a ResponseInterface so this is an object.

Phpstan doesn't know anything about the result - there is no installed dependency and no any version restrictions.

You can use get_debug_type instead.

What I'm thinking about - why should we stick with cherry-pick instead of merge? Merge will help to know that there are no missed commits in the history between old and new branches.

Oh in fact it does not know the dependency... I switched to get_debug_type in the merge.

Okay I will do a merge then:

• I moved the UploadMiddlewareUtils/ directory to src/
• I resolved the conflicts
